Vue state uses newspaper undefined in method

vuex uses mapstate to map state (attributeData: state = > state.kickoff.attributeData is used in the code), in the template < template VMI for = "(attritem, index) in attributeData" > you can use state to access state data, but in method you use this.attributeData and print, all undefined. I would like to ask why the attributeDatavalue cannot be obtained

template acquires data. If the mechanism of obtaining data in method is different, use the computed attribute to convert it:

computed:{
    attrData(){
        return state.kickoff.attributeData
    }
}
